Description

Air conditioner housing and indoor unit Technical Field

The utility model relates to the technical field of air conditioners, and in particular to an air conditioner housing and an indoor unit.

Background technique

At present, in order to increase the air volume and improve the heat exchange efficiency, zero wind sense air conditioners have added panel air outlet channels in addition to the air outlet. Due to the addition of the panel air outlet channel, the panel and the middle frame are suspended in the air, so that when this type of air conditioner is running in normal mode, the air guide door is opened, and the middle frame has a black leakage phenomenon from the user's visual point of view, and the structure is not tightly sealed and is not insect-proof, which affects the user's visual experience and the overall airtightness; in addition, because the panel and the middle frame are suspended in the air, when this type of air conditioner is running in normal mode, there is a problem that the wind blows to the panel, causing the panel to vibrate and generate noise.
